Synthesis method of 7-fluoroimidazo [1, 2-A] pyridine
-
Paragraph 0044-0049, (2020/12/29)
The invention discloses a synthesis method of 7-fluoroimidazo [1, 2A] pyridine, which comprises the following steps: by using 4fluoropyridine 2amine as a raw material, adding a chloroacetaldehyde water solution and alkali into a solvent at 35 DEG C, reacting in a micro-channel reactor for 510 minutes, and acidifying to obtain salt, thereby obtaining oxalate of 7fluoroimidazo [1, 2A] pyridine; thepreparation method comprises the following steps: dispersing oxalate in dichloromethane, and sequentially carrying out dissociation, purification and concentration to obtain the pure final product 7fluoroimidazo [1, 2A] pyridine. The synthetic method is short in route, raw materials are easy to obtain, operation is easy, and the conversion rate and safety are effectively improved. Post-treatment operation is simple, column chromatography treatment is not needed after each step of reaction, the product can be purified only through salification and dissociation, few waste materials are generatedin the production process, the environment-friendly requirement is met, and the method has important reference and practical value for actual enlarged production.
Synthesis method of 7-fluoroimidazole[1, 2-a]pyridine promoted by copper complex
-
Paragraph 0017-0019; 0020-0022; 0023-0025; 0026-0028, (2020/09/16)
The invention belongs to the field of organic synthesis, fine chemicals and medical intermediates, and particularly relates to a synthesis method of 7-fluoroimidazole[1, 2-a]pyridine from 2-amino-4-fluoropyridine and acetylene promoted by a copper complex. The method is characterized in that a copper complex is used as a catalyst, and 2-amino-4-fluoropyridine and acetylene undergo an oxidative cycloaddition reaction in the presence of a peroxide, so that 7-fluoroimidazole[1, 2-a]pyridine is synthesized. The method has the advantages of simple operation, cheap and easily available reagents, andgood industrial application prospect.
